, BRAKE-BEAM FOR RAILWAY-onus.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed December 12, 1913. Serial No. 806,150.

To all whom it may concern:

Be it known that I, SETH A. CnoNE, a citizen of the United States, and aresident of East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Brake- Beams forRailway-Cars, of which the following is a specification.

' The invention relates to improvements'in brakes for railway cars andthe like, and it consists in the novel features and structurehereinafter described and particularly pointed out in the claims.

The invention pertains more particularly to brake-heads adapted to carrythe brakeshoes and to the special means I provide for adjustablysecuring said heads on grooved. sleeves arranged on the ends ofbrake-beams.

The main object of the invention is to provide a very durablebrake-headlacking complexity and capable of being adjustably secured to the beamby very durable and inexpensive means adapted to thegroove in the sleeveon which the brake-head is mounted. v

The invention made the subject of this application embodies furtherimprovements on the invention disclosed in Letters Patent of the UnitedStates No. 1,073,220 granted to meSeptember 16, 1913.

The invention will be fullyunderstood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

Figure 1 is a side elevation of a portion of one end of a brake-beamhaving thereon a grooved sleeve, brake-head and securing means embodyingmy invention; Fig. 2 is a vertical section through the same on thedotted line 22 of Fig. 1; Fig. 3 is a detached face view of a keyemployed in accordance with my invention for securing the brake-headupon the beam, and Fig. 4 is an edge view of the same.

In the drawings, referring to Figs. 1 to 4 inclusive, 10 designates thebrake-head as a whole, and this head with the exception of the featuresembracing my invention may be of customary or any suitable form andconstruction. The brake-beam is numbered 11 and the sleeve thereon 12,said sleeve being formed with a circumferential groove 14 extendingpartly or entirely around the same, as usual, and receiving the head 10in a manner well understood.

The brake-head 10 is preferably formed with a back portion 15 which isopen at its center, as at 16, and said head has at one end of its openback a transverse opening 17 for one end of the key 18 and at the otherend of its open back a flange or member 19 for a bolt 20 which passesthrough the same and a hole 21 in the adjoining end of the key 18 andreceives a nut 22 by which the end of the key may be firmly forcedtoward said member 19 and its inwardly pro jecting bearing lugs 23, 24effectually bound against the sleeve 12 on which the head is mounted.The frontwardly facing wall of the opening or slot 17 is convexed andthe rear face of the lower end of the key 18 is concaved to fit andobtain a firm bearing against said wall, as shown in Fig. 2. The key 18is substantially vertical and formed with the transverse bearings 23, 24to enter the annular groove 14 in the sleeve 12 at points near the upperand lower ends of the opening 16 in the back portion of the head 10. Thekey 18 isslightly less in width than the groove in the sleeve 12 andalso slightly less in width than the opening 16 in the back of the head,and when said key is on the head it lies between two side flanges 26formed on said head and is exposed at its back, except at its lower endwhich is partly concealed behind the transverse bar or member 27,against which the end of the key has a firm hearing. The key v18 is asubstantially rigid structure, although capable of limited fiexion underthe pressure of the nut 122, as distinguished from a spring or flexibleI regard the key 18 as a distinct improvement over the key shown in Fig.7 of my aforesaid Letters Patent dated September 16, 1913, in that saidkey 18 has two widely separated bearing lugs 23, 24 to engage the sleeve12, said lugs being in line with the upper and lower horizontal portionsof said sleeve and affording advantages and a degree of efliciency whichrenders the head as a whole highly desirable. The upper lug 23 has acurved surface to engage the sleeve 12 b and the lower lug 24 ispreferably slightly curved to engage said sleeve. The middle portion ofthe key 18 or that part between the bearing lugs 23, 24 is cut away soas to create an elongated recess and avoid any contact of the keybetween the lugs 23, 24 with the sleeve 12. The setting of the sideedges of the key 18 between the flanges or integral sides 26 of the backof the head, is

12 or the part of the beam on which the head may be placed.

\Vhat I claim as my invention and desire to secure by Letters Patent,is:

1. In a brake beam, the combination with a brake-head having atransverse opening to slip over the end of the beam and rear wardly ofsaid opening and between the integral sides of said head a verticalopening communicating with said transverse opening, a part of the beamon which. said head is mounted, an independent substantially verticalkey in the back of said head extending along said vertical opening andhaving inwardly projecting separated bearin'g lugs bearing against theupper and lower horizontal portions of said part of said beam, meansengaging one end of said k'eih and means for forcing the otherend ofsaid key transversely toward theadjacent part of said head andsecuringit and comprising a bolt extended through ar portion of said head andsaid key and a nut on said. bolt for forcing said end of said key towardsaid part of said head.

2. In a brake beam, the combination with a brake-head having a slot in aportion of its back, the frontwardly facing wall of which slot affords afixed bearing, a part of the beam on which said head is mounted, anindependent substantially vertical key in the back of said headfulcrumed at one endon said bearing and having inwardly projectingseparated bearing lugs engaging the upper and lower horizontal portionsof said part of said beam, and means for forcing' the, other end of saidkey" transversely toward the adjacent part of said head and securing it.

3. In a brake beam, the combination with a brake head having a slot inthe lower portion of it's back, the frontwardly facing wall of whichslot affords a fixed bearing, a part of the beam on which said head ismounted,

an independent substantially vertical key in the back of said headfulcrumed at its lower end on said bearing and at its middle portionhaving upper .andlower bearing lugs projecting inwardly into engagementwith upper and lower horizontal portions of said part of said beam, andmeans for forcing the upper end of said key transversely toward theadjacent part of said head and securing it. i v g c 4. In a brake beam,the combination with a brake head having a slot in a portion of its backthe frontwardly facing wall of which slot affords a fixed bearing, apart of the beam on which said head is mounted, an independentsubstantially vertical key in the back of said head fulcrumed at one endon said bearing and having inwardly projecting separated bearing lugsengaging the upper and lower horizontal portions of said part of saidbeam, and means for forcing the other end of said key transverselytoward the adjacent part of said head and securing it, the back of saidhead having a vertical opening to receive the said key and admit thebearing lugs for engagement with the part of the beam on which the headis a mounted.
